PU1611 One Component High Bonding Auto Bus Glass Polyurethane Adhesive
PU1611 One Component High Bonding Auto Bus Glass Polyurethane Adhesive
●PU1611 is one component polyurethane adhesive with very good tensile strength and elasticity, primerless,can be used for Automotive and bus industry. High-bonding polyurethane adhesives for auto and bus glass provide permanent, weather-resistant, and structural bonding. These moisture-curing formulas absorb severe vibrations, resist extreme temperatures, and offer secure drive-away safety in as little as 1 to 24 hours
∎Key Features
●High Viscosity
●No DOP
●Primerless
●Odorless
●Excellent thixotropy, non-sag properties
●Fast adhesion to substrates
●Cold application
●One-component formulation
●Automotive OEM quality
●No oil permeated
∎Areas of Application
●Specially used for windshield and side glass of bus, car, railway vehicle (metro, high-speed rail), ship, spaceflight, engineering machinery vehicle, carriage and special vehicle
●For glass steel and plastic accessories (car roof, side body and car front)
●For bonding different material (such as metal, plastic, and glass) which requires high tensile strength and elasticity, the bonding can bear high mechanical deformation force
Industrial & Commercial Solutions: PU-1611 specialize in engineered polyurethane adhesives explicitly tailored for buses, coaches, and heavy railway vehicles.
Specialized High-Bond Glues: Adhesives like PU1611 provide high tensile strength and elasticity for large automotive, bus, and industrial applications
PU 6030 Light yellow translucent Polyurethane potting compound
PU 6030 is a two-component solvent-free polyurethane material at room temperature or heat curing. It is light yellow and transparent after curing. It is used for two-component sealing, filling, flame and other fields. The raw material does not contain heavy metals, green environmental protection, wide process operability, high physical properties of the finished product, and good adhesion to the substrate. Room temperature and heating curing can be, can be deep curing, curing less heat, low shrinkage rate; Excellent
flexibility after curing, with good flame retardant effect.
l Excellent low temperature characteristics, excellent weather resistance
l Excellent flame retardancy, 94 V-0
l Excellent electrical insulation, stability
Typical application
